Application June 16, 1953, Serial No. 361,925

3 Claims. (or. 98-43) binations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a side view of my improved skylight;

Fig. 2 is a sectional side elevation thereof; and

Fig. 3 is a plan view of certain parts, looking in the direction of the arrow 3 in Figs. 1 and 2.

Referring to the drawings, I have shown my improved ventilator as covering an opening H in a deck D. The ventilator has a base-plate which is preferably formed of plastic or other translucent or transparent material, and which directly overlies the opening H.

A relatively heavy casing has a circumferential flange 21 which rests on the plate 10 and which is secured to the deck D or other supporting structure by screws 24 which also pass through the plate 10.

The right-hand portion of the casing 20, as viewed in the drawings, is upwardly arched in substantially semispherical shape, and the left-hand portion is cut away to leave an open face 32 and also a ledge 34 which supports a slightly inclined plate 40. This plate 40 is also preferably of transparent or translucent plastic.

The outline of the plate 40 is clearly shown in Fig. 3, and the curved edge portion 42 thereof projects substantially within and beneath the arched portion of the casing 20.

A sleeve 50, which may also be of plastic material, is secured in a circular opening in the base-plate 10 as shown in Fig. 2, and this sleeve provides an open air passage to the interior of the structure to be ventilated.

Hollow raised portions 55 in the flange part of the casing 20 provide drainage passages which dispose of rain or water in any form which might enter through the open face 32 of the casting 20. The inward and upward projection of the sleeve prevents such water from passing through the sleeve 50, while at the same time air can flow freely over the open upper edge of the sleeve.

The provision of the transparent or translucent plate 40 overlying the transparent or translucent base-plate 10 and the hollow sleeve 50 admits a substantial amount of light through the ventilating skylight, and at the same time freely admits air but excludes water.

The interior or" the casing 20 is preferably painted or otherwise finished to reflect light and to thus increase the illumination furnished through the skylight.

The streamlined exterior of the ventilator renders it particularly adapted for use on sailboats as ropes and lines do not readily catch on the ventilator.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. A fixed ventilating skylight comprising a hollow casing member having substantially one-half of its semispherical upper portion cut away to provide an unobstructed air-admitting opening, said casing member having an annular lower flange and having fixed supporting ledges spaced above said flange and adjacent each edge of the air-admitting opening, a translucent protecting plate supported on said ledges and having its free edge extending within said casing opening, a translucent base plate underlying said annular lower flange of said casing member and permanently closing the area defined by said annular flange, except that said translucent base plate has an upstanding sleeve at its upper face which surrounds a substantial opening through said base plate and which defines an inner air-admitting opening beneath said protecting plate.

2. A ventilating skylight as set forth in claim 1, in which the annular flange of said casing member has spaced raised portions to provide drainage from the interior of said casing.

3. A ventilating skylight as set forth in claim 1, in which the translucent protecting plate is downwardly and outwardly inclined to facilitate exclusion of water from said casing.
